MACD is a two line indicator... dont use these bar indicators for it.. they are just someone in FF made it.. nothing substantial..
I stay with the historic and principally accepted way of use of a indicator..
And MACD is never read in a bar chart pattern.. always a two line thing .. like scotastics (Sp)..
And if you see the real MACD in the two line chart pattern with the price of GBP/USD in same line chart format, their is no divergence.. or maybe a slightly bullish divergence..
But at the Fundamentally charged markets like it is right now.. all these divergences dont stand much.. RSI, Candles and PA pave a better trade.
Just my opinion, all the best.
